It's hard since a lot of the casts are fragments of what they used to be besides discedo and mayfield. I can recommend some casts, though?
Asgard seems to have at least a decent cast. Mayfield always has a large cast, but quality varies and a lot of the really good players just dropped (but, there are still some amazing players.) Magicdraft has names I am familiar with and like, and discedo is mixed. I like some characters in the discedo, but some of the nations there fall flat and are very 1D. I'm biased and not found Mostly Harmless' cast for the most part. Some of the nations are really, really good and the others are kind of painful.
